The invention to be hereinafter disclosed relates to shower chines. J

Shower pipes of this general class are used for spray-washing incontinually showering the rapidly moving making-wires, felts and variousother parts of the paper making machines to keep them free from adheringfibres and foreign substances contained in the pulp. For economicalandefiiclent cleansm of I I I I I b paper making machlnery t isessentlal to shower the parts to be cleansed with an unbroken andforcefulsheet of'liquid. The

most universally used and recognized type r such shower pipes isdisclosed inthe Millspau'gh shower pipe Patents 7 82,680 and 7 82,755,both granted February 14, 1905, togetherwith his earlier Patents596,939,

596,940 and 596,941, granted January 4, 1898, which latter three havebeen considerably dis- 1 placed bythe two first mentioned In each ofthese examples a continuous sheet of the cleansing liquid is obtained bya discharge pipe having'a line of orifices and provided with sultahlenozzles, deflecting lips or planes angulary disposed to the-actions oftheis' suing jets or streams which infringe on said lips or planesandjthence discharge inthin sheets having diverglng sldes, the outeredges of which sheets all meet at the same line to form a continuous,unbroken sheet.

- struction, operation, and use of the invention,

The sizes and distances betweenthe O-I'ifiCP-s or dischargeiports andtheir positions relative to their deflecting planes determine the lineat which the several streams meet, and the shower'pipe is preferably solocated with relation to the parts to'be cleansed as to cause suchmeeting-line to lie on or approximately were made with rigid, fixed, orstationary defiectors. But, in the mills of the present time aconsiderably higher water pressure is used than in the earlier years ofthese later Millspaugh patents. The result is that in localities wherethere is any foreign matter in the There were objections to ed wit waterthe deflecting plate becomes grooved at pipes for paper makingma- Vforations first strike. As soon as a groove starts, the otherwisefanshaped sheet formed by that particular jet correspondinglynarpointswhere the jets issuing from the percorresponding strips orbands'of the wire or felt, leaving intervening unwashed bands;

The main object of the present invention is to avoid this serious defectand provlde a light, strong, erliclent and economical shower pipe inwhich the deflector plate may readily and easily'be adjusted tocompensate for the grooving tendency, or easily and quickly completelybe removed for renewal, when that becomes necessary. 7

To this end my invention consists, broadly of a shower-pipe having alongitudinal line of discharge-ports and closely adjacent thereto adeflecting plate or lip formed separately therefrom but longitudinally,slidably, keyed thereto in position to intercept and deflect in a singlecontinuous sheet the several separate j etsissuing through thedischarge-ports.

In order to more clearly disclose the conreferenceshould be had to theaccompanying drawings. forming partof the present application.Throughout the several figures of the drawings like reference charactersindicate the same parts in the several views.

In the drawings:

Fig. '1 isa side elevation of a pipe with the invention applied; 1"Fig.2 is an enlarged crosssection at right angles to the-longitudinalaxis and a slight'modification, V Referring to the drawings in detail,

.F 3 is a view similar to Fig.2," showing I i 1 indicates-the body ofthe pipe suitably mounted in well known manner and providh any desiredconnection to aisupply of water under pressure. This pipe is-drawn orotherwise worked to provide alongitudinally andhavinga snug fittherewith is the deflector plate 4 having the dove-tail channel or.groove 5 complementary to and receiving said rib. The metal of thechannel piece has-a slight degree of spring or yield as shown at 6. Thusshould :the :fit be tighter than desirable the zplate-will spread,slightlyandprevent bind-' wing. Likewise,*the-edges of the channelportions of the plate do not both fit snugly and iti 'htlyintoftheopposite angles of the rib or tongue. If one edge makes a snug fitthe other is slightly loose, .as clearly shown. Prefer- -ably, the onealong the side opposite the perforations is the looser one. Should theother zone be the looser, water might work back from the perforationsandbetween the rib and plate andcause rust or deposit and binding. Itwould also break the spray and destroy the continuity. of the sheet atthis point. It will be noticed that. the dove-tail :tongue and groove asformed in this "case, has no "sharp angles. Wherever there would be asharp angle there. is, instead, a gradual curve or rounded surface to,as n arly as practicable, entirely eliminate all binding at such points.i V V The operative part of the deflector plate is so inclined,positioned and directed with respect to the jet openings as to interceptthe jets, spread them into one continuous sheet, and when the spraypipeis properly mounted :in'its machine, deliver that sheet against the wirefelt or other part, at the point desired.

lVhile the sliding-fit between plate l and rib 2 is not'loose neither isit tight. Itis a snug fit and the plate may be moved longitudinallyyineither direction, by a moderate tap-on one ortheother end. Thus when anyevidence of'groovi'ng appears it is only necessary :towtaptheplate enduntil it'is moved a distance equal to the diameter'of one of theperforations, or very slightly more, thereby ibringing into'operation'anentirely fresh and unused plate surface forevery jet. When all parts ofthe plate have been used or, for any other reason a new plate isdesired, itmay be gsimplydrawlnoff and anewione substituted.

Obviously, plates of different inclination or design or otherwisedifferent may be'similarly substituted when desired.

Preferably, the rib 2 is die-lormed'by reducing the diameter-of the tubeor pipe. To more "readily get the dove-tail form -a. rod 7 maybe used,being held in thefol'd of the tube and thereby forcing the same into thefan or dove-tail form. This modification is clearly shown in Fig. 3.

It is thought that the construction, operation and use of the inventionwill be clear from the preceding detailed description wherein only apreferred form has been dis closed by way of illustration.
